' MACHINE FOR DRYING YARN AND TEXTILE GOODS.

To all whom it may concern:

Be it known that .I, ARTHUR Nonmsou MARR, a subject of the King of Great Britain and Ireland, residing at Rangiora, Thorner, near Leeds, in the county of York and King-f dom of England, have invented new and useful Improvements in Machines for Dry ing Yarn and other Textile Goods or Materials;

made to travel in an 1 both upwards and chamber.

This invention has reference to machinery employed for drying yarns in hanks, or other materials used in textile goods, or for the goods themselves, like, allof which are hereafter termed and included in the term materials. i

Hitherto in machinery employed for this purpose when rovision has been made for circulating air t irough the material operated upon, the said air has only been used for drying purposes, and it has frequently been upward direction or downwards in the drying This has the efl ect in some cases, where the current of air is too strong, particularly say, in the case of yarns, of causing the hanks to tangle, and in other cases causes the fibers to lie in the Wrong direction.

Further, no provision has been made'for' exhausting the air from the drying chamber, although in some cases attempts have been made to force or squeeze the moist air out of the dryingchamber through openings at or near its top by means of the pressure of the incoming heated air. Also, when the material has been; mounted u on pins, the latter have been fixed to trave ing chains to. which an intermittent traversing motion has been imparted. In these machines no provision has been made forcausing the pin or pole carrying the material to be intermittently revolved. Consequently, there has beenia danger of the water or other moisture in the material being allowed to collect or-remain locallyand unevenly in the material during the drying operation,

portions ofthe material. I 3 Various attempts have been m ade,.wi-tli more or less, success,,-to remedy the above defects, and the object'of, this ,inventionis to provide a machine in which-thetairfor dryingand also for conditioning the material afterwards is made to pass freely and as evenly as possible through the material being such as, hosiery and the? thereby deteriorating, I whennot actually in uring,..-such,portion or Specification of Letters Patent. Application filed July 20 1906.

'the poles through the In the hereinafter described machine the the 'drying chamber chamber,

Patented March 10, 1908. Serial No. 327,040.

Definite provision is also made for lntermittently revolving-the poles which support the material during the drying andv conditioning process so that the moisture shall not have time to collect at anyone point.

The requisite'number of of materiai to fill a pole in this machine can the drying process.

hanks or pieces be placed thereon while the machine is in motion and without stopping the traverse of drying chamber.

poles are arranged to be traversed longitudinally through the drying chamber, their ends being supported by races fixed to the sides of the drying chamber, and the poles are caused to be either continuously or intermittently moved through the same by'projections-fixed upon endless chains. Provision is also made for raising the poles by projections fixed to vertical lifting chains for conveying them successively to one or more races on a higher level and for finally returning them to the inlet end of the machine in,proper order for bein again traversed through the drying c amber. An

additional fan is also provided for the defi-' 'nite' purpose of exhausting, the moisture. in the drying chamber of the machine, and also for causing a slight movement of air into themachine from the room at the point where the operatives attending the machine;

stand. e I

By the above means the whole of the air in themachineis made to circulate alternately= through the material and the heating surface and it enables a greateramount" of. duty being obtained from a given amount of heating sui'faceJ .I attain theseobj'ects by the mechanism r the, accompanying drawings,

Fig. 9, an enlarged part elevation of means for intermittently rotating the poles. Fig. 10, a plan of the same. Fig. 1 1, a small diagrammatic view showing the arrangement of racks. A

The machine consists of an oblong drying chamber (1 having one of'its ends I) open, and the ,other end a closed, constructed with"- framing of timber, iron, or steel, in convenient sections lined and, covered in with boarding or other suitable material. The drying chamber is provided with a latticed or perforated'floor 33 and ceiling 34. On either or on both sides of the drying chambera is a narrower chamber d, e, but of equal length and height and of similar construction. In each narrower chamber is or are one or more fans f mounted on the same axis or shaft 9 constructed so as to move airparallel thereto, and so placed that they both draw their supply of air from the drying chamber a through openings or ports h at the bottom of the partition '11 between the two chambers as indicated by arrows in 3 and then pro el the air back into the drying chamber a through similar open- .mgs or orts 7' at the top of the same par tition, t us maintaining a continual circuilation of air downwards through the materi'alwhich is suspended from poles k in the drying chamber. Heating surface in the form of steam tuberadiators Z or coils is fixed in each. fan chamber, so that the air so circulated by the fans is heated, and

' ke t as hot as may be'desired.

I ture from the drying ,chambera s n'order to facilitate the escape of moisiding doors m are provided in the outer partition of each fan chamber at and near the o ening required opposite the pulley n for t e passing of the belt used for driving the circulating fans, and on the suction side of them. By these doors the uantity of air so drawn in b the fans may e regulated thus also re ulating to the same extent the rate at whic 1 the air in the machine shall be changed and renewed.

To give further control over the changing of the air inthe dryin chamber a, an additional fan or fans 0, i s. 2'and 3, may be fixed in any fan cham er, and separately driven at any desired speed, so as to draw its su ply of air from the bottom of the drying 0 amber. Two tiers of poles 7c o1- any multiple of two, say, four, in pairs, each pair consisting of an upper tier and a lower tier, and superposed, travel simultaneously through the drying chamber, the lower inwards, and the upper outwards, as indicated by the arrows in Fig. 1, along an upper race 1) and a lower race g, these races consisting respectively of one and of two bars of angle iron secure to each side of the dr ing chamber. At the open end I) of the mac line the lower bars of the lowermost race g project from the framin and on these bars the oles k from which tie material to be dried 1S freely suspended are placed by the attendant, one by one, so that they are taken forwards in succession by the endless traveling chains 1, one at each side of the drying chamber,-on which at short regular intervals are rovided rojections 8, Figs. 6 and 7, whic ropel t e poles 7r, at proper distances apart, etween the double'bars forming such lower race or races q, and upon the single bars forming the upper race or races 1).

The poles is when required may be caused, as they travel horizonta ly, to receive an intermittent or a continuous rotary motion by means of any suitable arrangement such as rings or ferrules 7c fixed to the ends of the poles is, as shown at Figs. 9 and 10. In the periphery of each ring k is formed a numer of elongated holes or recesses k at equal distances apart. The holes k are made to mesh with a number of rack teeth k cast, or otherwise formed, or fixed, to the race r, or to a projection fixed to the sides of the drying chamber. The teeth 76 are arranged in grou s at irregular or regular intervals apart, as s own in the diagrammatic view Fig. 11 so as to give the desired intermittent rotary movement to the poles 7c and conse: quently a more even and complete exposure of the material to the downward current of at the closed end 0 of the machine carrying other it provided on the lifting chains 12, Figs. 6 and 7. These lifting chains at the closed end of the machine have a vertical orbit or path being actuated by the larger sprocket wheels to which are keyed on the same shaft 11; as, and close to-and inside of similar but smaller wheels 3 which revolve freely on the same shaft and carry the traveling chains 1". One of such shafts 9c actuating a pair of lifting chains has also fixed upon it the worm wheel 2, Figs. 3 and 5, driven by the worm 1 keyed on the same shaft 2 as the cone 3 which is driven by another cone 4 at a relative speed corresponding to the position of the belt 5 connecting the two. The driving cone receives its motion through the pulley 6 on its shaft 7 from any convenient source.' The position on the tapered cones of the belt 5 which can be adjusted by any suitable belt motion, thus gives complete control over the speed of the whole of the chains and over the rate at which' the material travels throu h the machine.

'VVhen four tiers of poles 7c are employed, the shaft 2: has also keyed upon it such sprocket wheels as maybe re uired for driving at the same speed as itsel pitch driving chains 8 or otherwise, the shaft 9 carrying the sprocket wheels which actuate lifting chain 32 provided at the same end 0 of the machine for raising the poles kfrom a lower to a higher tier.

Fig. 8 shows the arrangement offour tiers, the material traveling while being dried four times the length of the driving chamber a. In .this case the lifting chains 11 at the open end I) of the machine are carried and actuated by sprocket wheels 9 keyed on the shafts 10, one on each side of the drying chamber, on each of which shafts on the fan chamber side of the partitions are also keyed two spur pinions 12 driven by two spur wheels 13 on the shaft 14 which is driven throughgearing from the cones 3, 4, as hereinafter explained. The traveling chains 1' are actuated directly by the sprocket wheels 15 at the open end 6 of the machine, and these are driven from the shaft :2: through bevel gear 16, Figs. 2 and 3, alongitudinal shaft 17 carried on bearings 1.8'on the outside of the fan chamber, and worm wheel 19 which is keyed on the shaft 14 on which are also fixed the said sprocket wheels15.

All the gearing used for connecting the traveling chains 1 with the lifting chains 1; and 111s so proportioned that the passage. upwards of any pole k by the liftmgchams is done in the same period of time which the traveling chains require to travel the pitch distance between any two successive poles propelled by them.

' On the upper bearings 20 of each shaft 22 the lifting chains 11 are short ascending races 1 21, Figs. 6 and 8, forguiding each pole /c after being lifted by the chains 1 into its proper place in the tier 7? of poles next above.

In order that all chains maybe kept taut,

as they lengthen by use or wear, one of the shafts over which each pair passes is made adjustable as to position, viz. the upper shaft of each pair at the inner or closed end and the lower shaft of each pair at the open end serve the lifting chains in this respect, and the traveling chains 1' are so adjusted at 23, 24, 25, of the open end of the machine by making adjustable the shaft which is the more suitable for that purpose. When the poles arrive at the outer end of the upper race, they are received from the chains on inclined bars 26 fixed so that the poles dc scend by gravitation to any convenient position.

In order to include in the same process the conditioning of yarn or other material after being dried as preferred by some, instead of placing the dried materials in a conditioning house, I provide an addition 27, Fig. 5, to the drying machine which may be described as follows. The upper part of the machine is prolonged at its open end I), the uppermost tier p of poles 7c being made considerably longer than the lower tier q, and above it is or are mounted a fan or fans 28 in a .close chamber 29 supplied through a duct or passage 30 with fresh air which may have been cooled, moistened, or otherwise treated so as to produce by its contact with the material the effect desired. This air current from the fans 28 is guided into contact with the material as that travels suspended on the poles 7c from the drying chamber a as far as may be required to the fixed inclined bars 26 before -mentioned down which the poles slide to a convenient place.

The action of the machine is as foll ows: The moving parts of the machine having 'been set in motion, the attendant hangs on and spreads out the required number of pieces 'of material upon each pole, which is then placed upon race g at the feed end of the machine and is carried forward along the race by the projections on the horizontal endless chainsm the direction of arrow shown at Fig. 1. The material is thus carried slowly through the drying chamber to its closed end and in so passing through the chamber the culating from the fan chamber vertically downwards through it are made to pass over and amongst the material operated upon.- When the oles carrying tie material have reached t e closed end of the drying chamber they pass into the curved portion t of the race q and are then caught by the projections on the vertical lifting chains 22 by which they are raised to the upper race currents of air that are 'cirp, and in-entering the latter race they are made to pass over the short race '21. The

poles are then carried again through the ma-' The material during its passage to and from each end of the machine may be acted upon by a rack or racks arranged along the said races, so that it may be turned at intervalsto prevent the water ormoisture settling at one point of the material. When a number of races are used, as shown at Fig. 8, the material after passing through the machine in. one direction is elevated to an u per race first at the closed end of the mac me and then after passing a second time throu h the machine is elevated at the open end t ereof for causing it to pass a third time throu h the drying chamber before it is again e evated at the closed end of the machine to the uppermost race. By these means the ma- 3'0 terlal maybe carried four or more times through the machine before it passes to the conditioning chamber and out ofthe ma chine. I claim: a 1.
